I got a MAS 49 / 56 where would you get 7.5x54 Dies? What cartridges can be modified for use reloading 7.5x54?

just found out the ammo isn't very common and I probably want to reload using military primers so I don't get slam fires, the brass is even spendy. I used to neck down 30.06 for my .270 and there has to be something compatible, like probably .308 which seems pretty close. I need someone who's expert in this because I'm not good enough to be the first to try it, lol. Any help would be majorly appreciated.

Forgive the factory ammo stuff, they mean well lol. You are obviously a shooter, factory ammo is a 4 letter word. You can't get serious accuracy on any gun without dialing in the loads. You have chosen arguably the best battle rifle in the world for reliability blended with accuracy, at least for the price, which will be going up. More reliable than an AR and more accurate than any AK derivatives. You avoided the easy .308 choice with a tad more juice even though it's one of the sweetest rounds known to man kind, because the mods are a hot mess, you are smart.

I know there are people like you out there who've figured this out because the rifle is too good for them to have not, you might find them on forums on the net. Put Red Meat out in the wilderness, something will find it for sure. Good luck
